Compiler Errors and Warnings
run-option
is CPU, LIB, MEM, PRI, STATUS, SWAP, or TERM. For more information, see the
RUN command in the TACL Reference Manual.
object-file
is the file name to contain the compiled filter. The default object file name is
FOBJECT, on the current volume and subvolume.
Considerations

If you omit the IN and INV parameters, the compiler prompts the TACL IN file—
typically a terminal—interactively for the filter specification.

If you omit the OUT and OUTV parameters, the compiler sends its listing to the
TACL OUT file—typically a terminal.

Filter object files have file code 845.

The compiler does not support the NOWAIT option. If you want NOWAIT
compilation, start a background TACL process. Use the background TACL, rather
than your interactive TACL, to compile the filter.

While trying to create a new object file, if the compiler finds an old object file with
the same name and file code, the new file replaces the old file.

When creating an object file, if the compiler cannot use the indicated file name, it
uses the name ZZEFnnnn (in which nnnn are four digits) and issues a warning
message.
Compiler Errors and Warnings
Compiler errors are classified as warnings, errors, or fatal errors:

Warning messages, which begin with *** Warning ***, describe a program
construct that is either incorrect or atypical. They help you identify sources of
potential trouble.

Error messages, which begin with *** Error ***, describe an incorrect construct.
After finding an error of this type, the compiler continues to run and to present
other error messages if appropriate.

Fatal-error messages, which begin with *** Fatal ***, describe situations originating
with the compiler in which the compiler cannot continue. You must correct the
problem and recompile to check that all compilation errors are found.

Messages that begin with *** EMF:, are fatal-error messages that originate with
TACL.
